Originally posted by osv legacy wide lenses on ff are a totally different story, it's the exact opposite situation :-/ full-on nightmare.
are you speaking generally across the board or more lens specific? I have a vivitar 28mm 2.8 that is beautiful on asp-c and that specific model(produced by komine iirc?) is very highly regarded for the price while other 28mm's showed less favorable results or had oily blades or such. how wide are you talking like fish eye or super wide like 18-22mm or up to like 28mm(~18mm ASP-c) and are you talking about experiences with other brand's digital ff's with brand or 3rd party lenses or pentax and others film cameras and brand or 3rd party glass? i know pentax's own line of legacy WA lenses is typically pretty highly regarded aside from a few, but older third party lenses were def much more sporadic.
I'm just wondering what your experiences were/are to make you feel this way. I'm not criticizing in any way. i have 0 film/ff experience. I'm just curious considering the implications it has with the new FF should i get one down the road. I would definitely consider some of the FA lineup at the very least, and depending on my needs, may extend to older glass like the A line's wider glass.
much appreciated.
